To all whom it may concern:`

Be it known that we,` CHARLES B. WALTON and GEORGE E. Pacon, citizens of the United States, residing at Trenton, in the county of Mercerand State of New Jersey, have invented certain new and useful Imrovements in Methods of Manufacturing iphon Closet-Bowls, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in the. method of manufacturing siphon closet bowls and in Van apparatus therefor.

The invention relates more articularly to the method of formi'n closet owls of the Siphon type, whereby t e bowl as a whole w en completed has asingle main seam extendin across `the same from front to rear, as distinguished from bowls heretofore constructed which have a multiplicity of seams.

The object of the invention is to provide a method of forming closet bowls whereby the proper shaping of the bowls and the unitin of t e parts can be readily and easily effected 'with but little trouble and with the minimum number of joints or seams.

In the drawings, Figure 1 re resents a plan View rof a one-half section of t e mold showing the repared material as fashioned tol fit the mo d, the upper leg of the sipho'n removed, but the position of the said upper wall is indicated 1n dotted lines. Fig. 2- 1s a section taken at right angles to Fig. 1 on line the method, we shall describe the artcu ar onstruction of mold which, brie y stated, onsists of the outer mold section A, shape to conform to-onehalf of a bowl and having its inner contour of the exact shape of the outer walls of the bowl. .l

B designates the lower art of the mold which may be in use attac ed to the upper part in any convenient or well known manner. This lower part has the channels for the base of the bowl.

C designates a removable mold part or former designed to be located in the lower leg of the slphon and which is convenientl made in section. This part C is of a lengtli Before describin slightly greaterthan thelength of the lower on passage so that the 4ends of the formery s1 will extend to the outer face of the outer Wall of the lower part of the bowl, as shown.

D designates a removable former located in the bottom of the bowl, its lower face being fashioned to conform to the lower wall of the upper leg of the Siphon. This upper conformer is made in section so that the same can be readily removed Vwithout danger of disfiguring the conforming surface.

E designates removable rmgs for the connecting rm s of the bowl.

The met .od of operation may be stated as follows: The operator places the material to form the bowl in the mold A and with suitable means presses the saine into conformity with the contour of the inner face of the mold, asis usual in this art. He then places y the removable conformer C at the oint where the lower leg of the Siphon is to located and applies the material, of which the bowl is formed, along the upper surface of the said conformer, so as to secure the exact and proper cross section of the lower leg. He then interposes the u per former'l) and fashions the lower part otP the bowl to conform to the under surface of said conformer, such act being readily performed, and the proper shape being aceuired while the half body of the bowl is stil within the outer mold. In placing the lower conformers C in position, the ends are projected 'so as to have the ends of the conformer rojecting beyond the sides of the rear part o the bowl. After the parts g5 have been properly formed to fit the'contour of the inner face of the mold and the curved surface of the formers, the bottom part B is laced on the mold and the base properly ashioned b well known mani ulating 9a methods. aving practically comp eted the `one half ofthe bowl, the companion half is likewise completed inI the same manner'and the two halves, including the formers, are brought face to face or edge to edge, the abutting ed es of the various parts of the bowl materia being cemented or connected in the well known manner. Duringthis act, the formers remain in position and maintain the walls adjacent thereto in proper position and i thereafter the lower former C is removed through the opening in the rear of 'the bowl, while the upper former is removed section by section leavlng the lower part of the up er leg ofthe Siphon. in its desired shape. he

, formers having been removed, the upper wall of the upper leg of the siphon is then placed in iositlon, havin previously been formed,l an is secured in t e usual manner by causing its edges to adhere to the inner laces of 11o the bowl, this upper wall being in width equal to the combined width of both sections of the bowl as originally formed. The molds having been removed, the bowl is then subjected to the usual treatment of firing and finishing. 5 From the above descri tion, it will be observed that the body o the mold itself is fashioned in but two parts, saving only the opening `at the lower part of the rear, which ppening is readily closed by a small sheet or m of the bowl material. W'e are enabled by the method above described, and as stated, to form the body in but two sections which are afterward united, and to fashion the inner walls of the si hon with exactness and without danger of eing improperly bent or twisted during the act of connecting, cementing, and uniting the two parts. It is also to be noted .that the making of the bowl in two parts has obviously advantages and may be used as well in connection with non-siphonic ,as well as siphonic bowls. Again, it 1s particularl to be borne in mind that the formers C and make it possible to secure uniformity of siphonic action and the'uncertain resultls of depending on the eye done away wit . Having thus-described the inventiomwhat v is claimed as new and desired to be secured by Letters Patent is y 1. The method of forming'siphon closet bowls consisting in placing the desired material in Elastic condition in a mold fashioned after t e manner of one-half of the closet bowl, creating ressure on the said material to vconform to t e inner surface of theV mold,

introducing a conformer at av point where the lower leg of the Siphon is to be located, applying the material of which the bowl is formed along the upper surface of said conformer, introducing a conformer above said applied material and working said material abo ut the lower surface of. the last mentioned conformer to form the lower surface of the upper leg of the si hom-applying a similarly formed section of t e bowl to the edges of the various i parts above formed while the conformers are still in position, subsequently removing the conformers, and finally applying sufficient material tothe inner surface of the connected sections to form the upper wall of the upperv leg ofthe siphon.

2. The method of forming siphon closet bowls consisting in placing the desired. material in lastic condition in a' mold fashioned after'tfie manner of one-half of the closet 55 bowl, creating ressureon the said material to conform to t e inner surfaceof the mold, introducing a conformer at a point where the lower leg of the Siphon is to -be located', with the outer end of the conformer projecting l throu h the material, applying the material of whlch the bowl is formed along the upper and side surfaces ofL said conformer, introducing an auxiliary conformer above said applied material and workingsaid material a out the lower surface of the last mentioned con'forner to lform lthe lowelr surface ofi tllie u ere oft esi on,a in asimiar fdilmed sction of tffie bow tibthegedges of thef various parts above formed While the conformers are still in position and the parts are in plastic condition, subsequently removing the conformers, then applying suflicient material over the adjoinmg edges of the connected sections to form the upper wall of the up er leg ofthe siphon, and finally applying su 'cient material to the opening formed by the projecting end of the first mentioned conformer to close the same.

In testimony whereof we aiiix our signa- S0 tures in presence of two witnesses.
